The goal of this observational study is to investigate the effects of sleep quality on cognitive flexibility, physical activity level, body awareness, and reaction time in individuals with Multiple Sclerosis. The main question it aims to answer is: Does sleep quality influence cognitive flexibility, physical activity level, body awareness, and reaction time in individuals with Multiple Sclerosis? Researchers will compare individuals with good and poor sleep quality to determine whether differences in sleep quality result in variations in cognitive and physical performance outcomes. Participants will complete standardized assessments of sleep quality, cognitive flexibility, physical activity, and body awareness, and will perform a computer-based reaction time test. In addition, participants will wear a wearable activity tracker for 7 days to objectively measure physical activity levels.

RECRUITINGSleep Quality (Pittsburgh Sleep Quality Index)
Sleep quality will be assessed using the Pittsburgh Sleep Quality Index. Total scores range from 0 to 21, with higher scores indicating poorer sleep quality.
Time frame: Baseline
Cognitive Flexibility (Stroop Test, TBAG Form)
Cognitive flexibility will be evaluated using the Stroop Test TBAG Form. Test completion time and number of errors will be recorded; longer completion times and more errors indicate lower cognitive flexibility.
Time frame: Baseline
Physical Activity Level (International Physical Activity Questionnaire-Short Form)
Physical activity level will be assessed using the International Physical Activity Questionnaire-Short Form. Total physical activity will be calculated in MET-min/week.
Time frame: Baseline
Physical Activity Level (Wearable Device)
Daily step count will be recorded using a wearable activity tracker. Average step count over 7 days will be calculated.
Time frame: 7 days
Body Awareness Questionnaire
Body awareness will be evaluated using the Body Awareness Questionnaire. Higher scores indicate greater body awareness.
Time frame: Baseline
Reaction Time (computer-based reaction time test)
Reaction time will be assessed using a computer-based reaction time system. Average response time to visual stimuli will be recorded, with shorter times indicating better reaction performance.
Time frame: Baseline
